Research Program and Experimental Facility for Rare Isotope Science

The Rare Isotope Science Project (RISP) has been launched in December 2011. The accelerator for the rare isotope science, which was named as KoRIA previously, utilizes both two typical RI production methods: 70 kW ISOL (isotope separator on-line), and 400 kW IF (in-flight fragmentation), in order to produce RI beams with high purity and high intensity near the neutron-rich drip line. The ISOL and IF systems are being designed to get a world-class RI beam intensity, which will give opportunity to study the exotic nuclei near the neutron drip line and to explore the unknown isotopes in the nuclear chart. A number of intense RI beams, e. g. about 109 pps for 132Sn in the energy range from 0 to 250 MeV/u, will be provided at the experimental halls for research. Proposed research program includes studies of the properties of exotic nuclei, the equation of state of nuclear matter, and the origin of the universe and process of nucleosynthesis. Various research facilities have been designed for the planned research subjects, which are Recoil Separator, Large Acceptance Multipurpose Spectrometer, Precise Isotope Mass Measurement System with Trap, Atomic Spectroscopy System, β-Nuclear Magnetic Resonance facility, etc. Based on the ISOL + IF + ISOL(trap) concept, distinct features of the new isotope and element research at KoRIA will be presented.
